Explanation:
Mechanical weathering is the physical disintegration of rock into bits and masses.
In this process, agents of weathering combines to fracture rocks into bits. There are different type of mechanical weathering. It is also known as physical weathering.
- Frost wedging occurs in temperate and polar regions where temperature is very low. Cracks in rocks are filled water and when the freezes it expands. As the water melts during summer and freezes in the winter, frost wedge forms.
- Salt crystal growth on rocks can cause mechanical weathering.
- Pressure release from the surface of rock leads to exfoliation domes.
- Wetting and drying of a rock leads to mechanical weathering
- Expansion and contraction of rock

No.
Explanation:
No, the increasing number of cell phones will not the cause of cancer because it emits low intensity of radio waves. Radiations such as x-rays, gamma rays, alpha particles, beta particles, and neutrons are responsible for causing damage to the cell and the main cause of cancer. High intensity of radio waves heats up the cells not causing cancer disease so we can conclude that the increasing number of cell phones will not cause cancer disease in humans.
